Project mention: Show HN: Spark, An advanced 3D Gaussian Splatting renderer for Three.js | news.ycombinator.com | 2025-06-11
BabylonJS and the OP's own Aframe [1] seem to have similar licenses, similar number of Github stars and forks, although Aframe seems newer and more game / VR focused.
How do Babylon, Aframe, Three.js, and PlayCanvas [2] compare from those that have used them?
IIUC, PlayCanvas is the most mature, featureful, and performant, but it's commercial. Babylon is the featureful 3D engine, whereas Three.js is fairly raw. Though it has some nice stuff for animation, textures, etc., you're really building your own kit.
Any good experiences (or bad) with any of these?
